CompTIA CASP+ (CAS-004) — Question 280

A web service provider has just taken on a very large contract that comes with requirements that are currently not being implemented. In order to meet contractual requirements, the company must achieve the following thresholds:

• 99.99% uptime
• Load time in 3 seconds
• Response time = <1.0 seconds

Starting with the computing environment, which of the following should a security engineer recommend to BEST meet the requirements? (Choose three.)

Answer options

• A. Installing a firewall at corporate headquarters
• B. Deploying a content delivery network
• C. Implementing server clusters
• D. Employing bare-metal loading of applications
• E. Lowering storage input/output
• F. Implementing RAID on the backup servers
• G. Utilizing redundant power for all developer workstations
• H. Ensuring technological diversity on critical servers

Correct answer: B, C, H

Explanation

Choosing B, C, and H is optimal for meeting the specified requirements. A content delivery network (B) can enhance load times and uptime by distributing content closer to users. Implementing server clusters (C) ensures high availability and resilience, while ensuring technological diversity on critical servers (H) helps mitigate risks associated with hardware or software failures. The other options do not directly contribute to the key metrics of uptime and response time.
